Why would they intentionally screw up so badly idk.

"Never attribute to malice that which is adequately explained by stupidity."

They probably started with an overambitious design, took some ill-advised short-cuts, and pivoted the to the "extraction" format after they'd already marketed it as a different concept, and made a bad gamble or two. Normal gamedev stuff. Same as every Molyneux game.

A few years back this could've been another No Man's Sky story where they fix it after launch... but that means going deeper and deeper into debt while you salvage the mess you've made. Post-COVID interest rates make that impossible. So now they're broke and the project they spent the last years on is a stinker and they don't have enough runway to fix it.

So they're done.
